Description

 Communication method with transmission of additional information

The present invention relates to a communication method with transmission of additional information, in which a call process is carried out by means of a first subscriber station in order to establish a communication context with a second subscriber station for the transmission of data or information, wherein additional information is transmitted to the second subscriber station, the audio, Image or video data or control data.

In the known communication method of a communication system, such as telephones, mobile phones, ^PDAs, computers, etc., information is transferred different kind between the subscriber stations may contain information Multimedia for example voice, image information, video information or general. The transmission of additional information plays an increasingly important role. For example, additional information in the form of advertising can be transmitted to the subscribers, thereby reducing the communication costs for the subscribers.

In particular, there is a need for subscribers of modern communication systems to send individual audio, video or video data to other subscribers, for example to transmit personal multimedia messages. This need exists both in the home and business, where, for example, an image of the caller or an audio or video file associated with the caller is transmitted as additional information to one or more subscribers.

It is the object of the present invention to specify a communication method which offers an increased attractiveness for the subscribers as well as for advertisers and is used more frequently. This object is achieved by the communication method according to claim 1. Further advantageous features, aspects and details of the invention will become apparent from the dependent claims, the description and the drawings.

In the communication method according to the invention with the transmission of additional information, a call process is performed by means of a first subscriber station to establish a communication context with a second subscriber station for the transmission of data or information, and additional information is transmitted to the second subscriber station comprising audio, image or video data wherein the additional information is defined by the first subscriber station and transmitted to the second subscriber station already before or during the call process, and the additional information is output at the second subscriber station as a signal for displaying the call.

This allows the called party, even before the call is accepted, to recognize multimedia information of the caller, such as a personal business card or a personal ringing tone of the caller, which is issued to the called party. The called subscriber thus has an improved possibility of deciding whether to accept this call or not. In particular, the caller can, for example, determine the ringtone generated by the called subscriber by means of the inventive communication method. For the participants offers an increased attractiveness, since each ringing signal can be designed individually by the caller and ensures an individual appearance at the called party.

Furthermore, the transmission of the additional information can be billed separately by the service provider. The additional information may also include, for example, advertising messages, the communication costs being wholly or partly borne by the advertiser and the participants Communication service at a reduced price or at a lower cost.

By way of example, the additional information can be transmitted from the first subscriber station to the second subscriber station. This has the advantage that the additional information is created, for example, at the first subscriber station and transmitted directly from there as a call signal to the second subscriber station.

Alternatively, the additional information may be retrieved by a control signal originating from the first subscriber station from a data memory coupled to the second subscriber station. In this variant, there is the advantage that in the first subscriber station no large amounts of data must be stored and still no large amounts of data must be transmitted from the first subscriber station to the second subscriber station.

Advantageously, the additional information is selected by means of the first subscriber station from a number of stored templates. As a result, the additional information can be quickly provided by the calling subscriber for sending. In this case, the additional information may be stored, for example, in a central data server of the communication system or locally in a memory of the subscriber station.

The additional information can also be created, for example, by means of the first subscriber station. This allows a subscriber to send, for example, currently created images or videos or sound recordings as additional information to the second participant who signal there the incoming call.

Preferably, the additional information is modified by means of the first subscriber station in order to transmit, for example, individual messages of the first subscriber station in the additional information. This can, for example Advertising messages are linked as additional information with personal messages of the calling party, so that the advertising message appears together with the personal message of the caller as a call signal at the second subscriber station or the called party.

Advantageously, it is automatically checked before displaying the additional information at the second subscriber station, whether the display of additional information is allowed or prevented. This allows the called party to ensure that he is not bothered by unwanted additional information, such as unwanted ringtones. Preferably, the method offers the possibility of allowing special or incoming individual ringtones only at certain times, for example only outside the working hours of the called party. Also, the permission may refer to certain callers, such as callers or caller groups, whose numbers are stored in the address book of the called party. Furthermore, the permission to display the additional information can refer only to special callers, which has allowed the display of their additional information to the own subscriber station explicitly.

Preferably, the additional information is stored in one of the second subscriber stations associated data memory and output in future incoming calls as a call signal. As a result, additional information of certain subscribers, such as a particular individual ringtone of the caller and / or displayed on a display multimedia business card, are repeatedly displayed as a call signal to the recipient when the subscriber calls or wants to establish a communication context with the subscriber station of the recipient.

For example, the additional information may also include a purchase offer that is issued at the second subscriber station, and it may be sent from the second subscriber station, a signal for accepting the purchase offer to a central data processing unit of the communication system. As a result, products and services can be purchased directly and in an uncomplicated way. In other words, a called subscriber can react directly to the additional information designed as advertising and purchase the desired product. The advertiser has the advantage of a particularly targeted and effective advertising.

Advantageously, after the signal has been sent to accept the purchase offer, a signal for activating the additional information for use by the second subscriber station is generated. As a result, the second subscriber, for example, acquire a particularly attractive additional information, which he can then use for himself to announce his calls to other participants. That is, the called party may, in particular, acquire tunes, video sequences or pictures to use as a call signal in future own calls. By this measure, an increased fun factor is achieved in the participants, which goes far beyond the previously known use of ringtones in your own device. This results in significant economic benefits for both the operator of the communication service as well as for the providers of music and video files.

Preferably, after the transmission of the signal for accepting the purchase offer, a fee reduction signal is generated and assigned to a subscriber station, in particular the second subscriber station. This may make the purchase of a product even more attractive to the subscriber, for example, by receiving a bonus for using the communication service when making the purchase.

For example, the additional information can be transmitted by a data transmission to the second subscriber station prior to call signaling. This has the particular advantage that already valid standards can be used in the call signaling and in the transmission of the ringtone. The additional information can also be transmitted together with the call signaling to the second subscriber station. As a result, the ring tone or the individual audio call signal always arrives synchronously with the incoming call. Furthermore, a billing is made possible because the additional information or control information that is sent with the call signaling, for example, can be evaluated at a switching device.

In the call signaling, a control signal is preferably transmitted to the second subscriber station, which at the second subscriber station by means of a

Comparison circuit is interpreted to effect the output of the additional information. This procedure also offers billing benefits, as the

Control information that is sent with the call signaling on one

Switching device can be evaluated. For this purpose, the control signal is extracted in the switch and to a

Billing system transmitted.

According to an advantageous embodiment of the communication method, a control signal is transmitted with the call signaling to the second subscriber station and evaluated there to select audio, video or video data from a data store and output as a signal to display an incoming call.

For example, at the first subscriber station from a database, a multimedia additional information or even a ringtone, etc., to which a control signal is assigned. In this case, only the control signal is transmitted, which on receipt at the second subscriber station leads to the extraction of corresponding additional information from a database of the second subscriber station, the additional information corresponding to the transmitted control signal appearing as a call signal for signaling the incoming call to the second subscriber station , Even with this method, accurate billability is possible if the Control information that is sent with the Rufsignalisierung is evaluated at the switching device.

Also, this embodiment of the method has the advantage that no large amounts of data must be transmitted, such as audio data as ringtones, etc. Therefore, this method can be implemented with reduced effort.

Advantageously, a plurality of additional information is stored in the first and / or in the second subscriber station, wherein the

Additional information can be updated at intervals by a central data server of the communication system. In this way, the user can always see the latest ringtones or audio data or even visual

Information or data are offered because the offer can be updated regularly via the data server. Furthermore, an accurate billing is possible if the control information that is sent with the call signaling are evaluated at a switching device. In addition, even in this case when carrying out the method according to the invention no larger data packets must be transmitted, d. h., The inventive method can be implemented with relatively little effort.

Preferably, before the transmission of the control signal to the second subscriber station an interrogation signal is sent to the second subscriber station, which causes the transmission of selection information for selecting possible audio, BiId or video information to the first subscriber station, and then made a selection by means of the first subscriber station and one of Selection corresponding control signal transmitted to the second subscriber station.

This allows the called subscriber to determine for himself which types of ringtones or generally audio or video data he wishes to receive as call signaling. That is, the called party sends a possible

Selection to the calling subscriber, so that this from the appropriate Can choose offer. In this embodiment, a precise billing is possible because the control information that is sent with the call signaling, for example, can be evaluated at a switching device. In addition, even in this embodiment of the method, no larger data packets must be transmitted and thus the method can also be implemented with reduced effort.

This method can advantageously be used in speech dialogue systems (voice portals) in order to give the user with the additional information provided for selection an improved navigation through the speech dialogue system.

Advantageously, the additional information is transmitted from a central data server of the communication system to the second subscriber station, wherein a request signal from the first subscriber station is previously sent to the central data server. As a result, the user can always be offered the latest ring tones or signaling files or generally call signaling cards, since the offer is always requested by the server. The server-based system also allows accurate billability.

Preferably, the reception of the request signal in the central data server causes the transmission of a selection signal from the central data server to the first subscriber station, which enables the selection of additional information via the second subscriber station at the first subscriber station, and then a trigger signal for initiating the transmission of the selected additional information sent from the first subscriber station to the central data server, which causes the transmission of the additional information to the second subscriber station. This offers the user the advantage that a current selection of existing additional information is provided, from which he can select the appropriate additional information in order to use it as a call signal to the called party. Again, there is a precise billability due to a server-based system. Advantageously, the additional information from the central data server to the second subscriber station is sent together with an identifier of the first subscriber station, and additionally sent, for example, a call signaling from the first subscriber station to the second subscriber station, in particular after receiving the call signaling to the second subscriber station, the additional information as a signal for a incoming call is issued.

By this measure valid standards can already be used in the call signaling and in the transmission of the ringtone. The billing of calls with signaling by additional information can be realized by a specific rating. In particular, additional information can be provided by its own service provider. It can also operate a separate server, which implements the news.

The invention will be described by way of example with reference to the figures, in which

Figure 10 shows a further embodiment of the method according to the invention, in which the additional information is sent before the call signaling from the first subscriber station via a data server to the second subscriber station.

FIG. 1 shows a first exemplary embodiment of the method according to the invention. At a first subscriber station 11, such as a mobile device or terminal, initially a selection of the desired subscriber by entering the call identifier or by selecting from the address book (step 1). This is followed by the creation of additional information. This can be done, for example, by selecting a ringtone, a video, an animation or other multimedia data. However, the additional information may also be created by recording a ringtone, a video or by selecting a background image, a video or an animation and entering a personal message (step 2). Then the call process is started (step 3). Now, the additional information is transmitted in or before the call process (step 4).

At the second subscriber station 12, which is also a mobile telephone, for example, the reception and the evaluation of the additional information takes place (step 5). If an option for outputting the transmitted additional information is activated at the second subscriber station, these are output instead of the set ringtone or picture or video (step 6). Now the called subscriber at the second subscriber station 12 can decide on the basis of the additional information output whether he accepts or rejects the call (step 7).

Thus, the caller at the first subscriber station 11 can determine the ringtone or the additional information displayed or played on the called subscriber at the subscriber station 12 and personalize the call. The called party to the second subscriber station 12 can better decide by the additional information whether he wants to take the call. The additional information can be billed separately by the provider of the communication service.

In order to prevent the called subscriber at the subscriber station 12 from being bothered with unwanted ringing tones, audio signals or the like, permission data is contained in the second subscriber station 12 in a comparison memory not shown in the figure. The permission data contains information about call times, special ringtones, callers or caller groups or numbers in the address book. In the case of an incoming call, the call data or the times are compared with these data in the comparison memory and, accordingly, the output of the Additional information allowed or prevented at the second subscriber station 12.

FIG. 2 a shows further details of the first exemplary embodiment from the start of the method to the transmission of the additional information. After the start of the procedure, the subscriber A enters at the first subscriber station 11 an identifier of the subscriber B or selects B from his address book (step 1). In the next step (step 2), the additional information to be selected, for example, a ringtone, or information about this additional information, such as a ringtone, is displayed. the name of the ringtone, the type of file, or a sample, either read from memory or recreated. In this case, the additional information can be read from a memory of the first subscriber station 11, or from a memory of the second subscriber station 12, or from an external server. If the additional information is recreated, nothing is read.

The subscriber A at the first subscriber station 11 can now perform either step 3a or step 3b. In step 3a subscriber A selects additional information. The selection is made either from their own additional information, such as their own ring tones or data cards, or from a special offer of additional information, such as. Specially released ringtones or data cards. But he also has the opportunity to select the additional information from a special selection of the participant B. Alternatively, the subscriber A creates a new additional information, for example by recording his own ringtone or creates his own picture or text message (step 3b).

Subscriber A can now optionally further personalize the additional information. For this purpose, participant A supplements the selected or created additional information by specifying or recording or modifying the additional information, for example by entering a text message in a selected data card for display (step 4). Now the subscriber A starts at the first subscriber station 11 the call to the subscriber B at the second subscriber station 12 (step 5). Subsequently, the additional information is transmitted before or during the call process to the 5 subscriber B at the second subscriber station 12 (step 6).

The sequence of the steps shown above can also be performed in a different order, i. that, for example, the additional information is assembled first and then the subscriber B to be called is selected.

I O

FIG. 2b shows in detail the further method steps from the transmission of the additional information to the output at the second subscriber station 12. After the additional information has been transmitted to the second subscriber station 12, the additional information is received there and evaluated (step 7).

15

It is then determined whether the output of the received additional information is allowed (step 8). This is done by comparing the caller ID of the subscriber A with the default settings on the second subscriber station 12. The license is dependent on one or more 0 of the following factors:

a) general permission, i. the additional information is e.g. always issued, b) membership of the call identifier to the address book,

C) membership of the call identifier to a category or group, d) specific setting for the call identifier, e) time of receipt of the call, (for example, the additional information should be received only in the evening), f) status of the subscriber station 12 or the current Environmental parameters 30 such as light or noise. In each case, it is possible to specify in the presettings whether the output of the additional information as a whole, in parts or not is permitted (step 8).

If it is determined by the comparison circuit that the output of the additional information is allowed, the additional information of the subscriber A is output from the subscriber station 12 of the subscriber B and replace there

Presets on the subscriber station 12 either only for this current

Call or for this current call and all other calls of the subscriber A

(Step 9). Subscriber B can now decide whether to accept or reject the call (step 10).

In Figure 2c, the further course of the method according to the invention according to the first embodiment is shown in detail. If the call acceptance is by B, a voice connection is established between the first subscriber station 11 and the second subscriber station 12. In this case, the additional information, for example an image or video information, optionally further displayed (step 11). Subsequently, the voice connection or the speech context is terminated (step 12).

In the event that additional information has been output which can be acquired by the subscriber B at the second subscriber station 12, the following steps are still carried out:

The information for the offer is either determined from the additional information received or queried by a server. The offer may include the acquisition of data and / or entitlements. For example, the additional information played, in particular ring tones, pictures,

Video clips or data cards to be purchased. But it can also be with the

Additional information linked objects, such as the ringtone belonging piece of music, a video clip, data or fun cards or fun objects are purchased. (Step 13). It should be noted that ringtones are freely distributed as an advertising medium for music or other products. If the subscriber A uses this ringtone to call the subscriber B, the subscriber B is automatically made the offer to buy the advertised product.

There is the issue of an offer on the subscriber station 12 of the subscriber B, for example, to buy the heard ringtone. (Step 14). If subscriber B wishes to accept the offer, a server, e.g. the additional information, such as ringtones, etc. or additional information plus an activation information transferred. However, additional information that has been unlocked, such as a ringtone with built-in authorization to be transmitted, or only the activation takes place, for example if the additional information has already been transmitted and stored, e.g. in Digital Rights Management (DRM) systems that separate content and entitlement (step 15) as specified, for example, by the Open Mobile Alliance.

Finally, the server instructs a bonus system to credit subscriber A with a bonus. The information about the credit is issued on the subscriber station 11 or the terminal of the subscriber A. (Step 16).

FIG. 3 schematically shows the sequence of the method according to the invention in accordance with a further exemplary embodiment. First, a message is generated at the subscriber station 11, e.g. an SMS or MMS containing a ringtone and an associated rule. The rule may e.g. "If the caller's caller ID is the same as the caller ID of A (ie, CLI = A) then play the attached ringtone." (Step 1) Now, a communication context for data transmission is established (Step 2).

In step 3, information for a billing system in a switch is detected and generated. It includes the Switching device, for example, a SIP Application Server (Session Initiation Protocol Application Server, as they are available in future mobile systems).

Finally, the message is received and interpreted at the second subscriber station 12. It waits until the rule, such as CLI = A, is satisfied (step 4).

Finally, the call signaling takes place from the first subscriber station 11 to the second subscriber station 12 (step 5). If the rule is met, then at the second subscriber station 12, instead of the normal ringtone, the received ringtone will be played once or every future time. (Step 6).

This method has the advantage that the already valid standards can be used in call signaling and in the transmission of the ringtone.

FIG. 4 shows a further possible embodiment of the method. Initially, the first subscriber station 11 integrates the ring tone into the call signaling, e.g. CLI (step 1). Now follows the call signaling from the first subscriber station 11 to the second subscriber station 12, for example CLI with ringtone (step 2). The control information is extracted in a switch and forwarded to a billing system (step 3). Finally, the reception and interpretation of the call signaling takes place with the ringtone (step 4). At the second subscriber station 12, the received ringtone is played instead of the preset ringtone (step 5).

With this embodiment, a billability is possible, since the control information that is sent with the call signaling, can be evaluated at a switching device. The ringtone always arrives synchronously with the incoming call. FIG. 5 shows a further possible embodiment of the method. In this case, a message is initially generated at the first subscriber station 11, such as an SMS or MMS message containing a ringtone (step 1). Now the generated message is sent (step 2). Then the message is received and interpreted (step 3). At the first subscriber station 11, a supplement to a control information in the call signaling takes place (step 4). Finally, the call signaling takes place from the first subscriber station 11 to the second subscriber station 12, for example a CLI with control information (step 5).

The control information may be extracted in a switch and forwarded to a billing system (step 6). Now takes place at the second subscriber station 12, the interpretation of the control information in the call signaling (step 7). Finally, the playback of the received ringtone at the second subscriber station 12 takes place in place of the preset ringtone (step 8).

This refinement of the method also offers the advantage of precise billability since the control information that is sent with the call signaling can be evaluated at a switching device.

FIG. 6 shows a further advantageous embodiment of the method according to the invention. In this case, the first subscriber station 11 is assigned a database 120. The database 120 is, for example, a data memory provided in the first subscriber station 11. First, a selection of additional information from the database 120 is performed at the first subscriber station 11 (step 1). Now, the integration of control information in the CLI, for example, information about games, or a certain defined ringing tone occurs (step 2). Now the call signaling takes place from the first subscriber station 11 to the second subscriber station 12, for example a CLI with control information (step 3). At the second subscriber station 12, the control information is interpreted in the CLI (step 4). Accordingly, an additional information is extracted from a database 121 which is assigned to the second subscriber station 12 or is provided in the second subscriber station 12. In this case, the additional information corresponds to that additional information which the subscriber A has selected at the first subscriber station 11 (step 5). Now, at the second subscriber station 12, for example, the received ring tone instead of the preset ring tone is played back according to the additional information (step 6).

This refinement of the method also offers the possibility of accurate billing since the control information that is sent with the call signaling can be evaluated at the switching device. In addition, when carrying out the transmission, no large data packets need to be transmitted, e.g. Ringtones, etc., which is why the method can be implemented with relatively little effort.

FIG. 7 shows a further advantageous embodiment of the method according to the invention. In its course, this method essentially corresponds to the method shown in FIG. 6, but the databases 120, 121 of the first and the second subscriber stations 11, 12 are updated regularly (step 7). For this purpose, the updates to the databases 120 and 121 are transmitted from a data server 130. Furthermore, in this figure, the extraction of the control information is shown, which takes place in a switching device. The control information is passed on to a billing system (step 8).

By means of this embodiment of the method according to the invention, the user can always be offered the latest ring tones or cards since the offer can be regularly updated via the data server 130. Furthermore, a billing is possible because the control information that is sent with the call signaling, evaluated at the switching device can be. In addition, in carrying out the method, no large data packets between the subscriber stations 11, 12 must be transmitted, so that the method can be implemented with relatively little effort.

FIG. 8 shows a further particularly advantageous embodiment of the method according to the invention. Initially, starting from the first subscriber station 11, a request for transmission of a ringtone selection to the second subscriber station 12 takes place (step 1). Following the request, the ringtone selection is transmitted from the second subscriber station 12 to the first subscriber station 11 (step 2). The selection of additional information from the repertoire of the second subscriber station 12 (step 3) now takes place at the first subscriber station 11.

Now, at the first subscriber station 11, the integration of a control information to the CLI, wherein the control information, for example, information about certain games or ringtones, videos, image files, etc. contains. (Step 4). Now the call signaling takes place from the first subscriber station 11 to the second subscriber station 12, for example the CLI with the control information (step 5). Optionally, the extraction of control information in a switching device and the transfer of information to a billing system (step 6).

In the second subscriber station 12, the control information is interpreted in CLI (step 7). Accordingly, additional information is extracted from the data memory 121 of the second subscriber station 12, which corresponds to the previously made selection at the first subscriber station 11 (step 8). Now, the playback of the received or the extracted ringtone tone instead of the preset ringtone sound at the second subscriber station 12 (step 9).

Also, this method offers the possibility of accurate billing, since the control information that is sent with the call signaling, at the Switching device can be evaluated. Furthermore, even in this case no large data packets must be transmitted, so that the method can be implemented with relatively little effort. In addition, the called subscriber at the subscriber station 12 can himself determine which types of ringtones he wants to hear.

Another particularly preferred embodiment of the method will be described with reference to FIG. Initially, a request is generated at the first subscriber station 11, which request is sent to an object data server 140. (Step 1). Subsequently, a selection of possible additional information is transmitted from the objects 140 to the first subscriber station 11 (step 2). At the first subscriber station 11, a command is now generated which is sent to the object data server 140 and causes it to transmit additional information to the second subscriber station 12 (step 3).

Now the call signaling from the first subscriber station 11 to the second subscriber station 12 takes place (step 4). At the second subscriber station 12, the preset ring tone is suppressed, and instead, the additional information or the ringtone transmitted from the object data server 140 is output (step 5). For this purpose, a request is made to the object data server 140, which is generated by the second subscriber station 12 and sent to the object data server 140 (step 6). In addition, information is transmitted to a charge / bonus system from the object data server 140 (step 7). The additional information is transmitted from the object data server 140 to the second subscriber station 12 (step 8).

The individual process steps shown here are not linked to a specific sequence, but can also be carried out in different order of magnitude, depending on the given conditions. Also by this method, the user can always be offered the latest ringtones or cards, since the offer is always queried by the object data server 140. Also is This server-based system enables accurate and good billability.

Finally, FIG. 10 shows a further possible embodiment of the method according to the invention. It is first at the first

Subscriber station 11 generates a message, such as an SMS or MMS.

The message contains a ringtone and the number of the second

Subscriber station 12 (step 1). The message is from the first one

Subscriber station 11 to the object data server 150 shipped (step 2). Now, a message is generated at the object data server 150, which contains the received ring tone and the identifier of the first subscriber station 11 (step 3).

In addition, there is another possible embodiment of the method according to the invention. In this case, a message is initially generated at the first subscriber station 11 an SMS or MMS. The message contains a stand-alone beep and the number of the first - sent - subscriber station 11 and the (step 1). The message is in this case sent over asynchronous SMS / MMS transmission channels, and initiates only retroactively a caller of the subscriber B. When the call back message at the subscriber B, so the subscriber can view the sent call-back SMS from subscriber A. , In this case - initiated automatically by the opening of the call-back message from subscriber 2 - is triggered by an additional device direct call back to subscriber A and an additional confirmation that the message was viewed. The automatic call-back function initiates the call setup to subscriber A and can be recognized by a ringback tone. The call charges are charged to subscriber A because he has initiated a call intent by sending the call back message and subscriber B is automatically connected to subscriber A upon opening the call back message.

Furthermore, information is passed on to a billing / bonus system (step 4). Finally, the message sent is sent from the object data server 150 to the second subscriber station 12 (step 5). There, the reception and extraction of the ringtone and the identification of the first subscriber station 11 takes place (step 6).

Starting from the first subscriber station 11, a call signaling of the first subscriber station 11 to the second subscriber station 12 takes place (step 7). When the ringtone is received by the object data server 150 with the ID of the first subscriber station 11, it is output instead of the normal ringtone at the second subscriber station 12 (step 8).

Also in this particular embodiment of the method, the already valid standards can be used in the call signaling and in the transmission of the ringtone. The billing of such calls with additional information can be realized by a specific rating. Furthermore, it is possible to realize the call with the additional information contained as a service provider or to operate its own server that implements the messages.
